If you're using first-class land for biofuels, then you're competing with the growing of food. And so you're actually spiking food prices by moving energy production into agriculture.

It's amazing how one introductory course in environmental science can turn a 20-year-old into an Biofuels expert.

Biofuels such as ethanol require enormous amounts of cropland and end up displacing either food crops or natural wilderness, neither of which is good.

We have to use cars much more efficiently. We have to look at alternative technologies of cars such as biofuels or, even more importantly, electric cars.

It is critical to develop a biofuel industry powered by feedstocks produced in every corner of the country in addition to the Midwest. That is why USDA has established five regional research centers working on science necessary to ensure profitable biofuels can be produced from a diverse range of feedstocks.
